i need help how to set points on force 50

[forty5goingon65]

i took my points off to clean them. on the shaft there is a line before the high point do i set my points from the line or from the high point thanks

Re: i need help how to set points on force 50

I hate to see a 0 reply and I feel qualified help is on the way. Meanwhile, I posted the old post at the bottom and attached a pic related to your question on my 35 hp Chrysler vs your 50 hp Force. I?m questioning my info since I?ve never had a timing issue. I have the following questions since I have not been in a good manual since 1985 or had a real point or timing issue. I?ve checked and cleaned my points every 3-5 years and possibly changed them once. As Frank said, ?the old points have been very reliable? w/o ever failing once. The motor has always started instantly and led me to think the timing was fine. Now, I question the timing related to top performance and standard tune-up procedure. Due to, the lack of having my original Chrysler manual and post on this site. Such As:

1. Setting the points properly is not setting the timing? Timing should be checked or set after the points are set?
2. Timing is basically not affected unless the point gap is off or excessive wear has occurred?
3. Are the points set at the highest point on the cam lobe or at a specified timing other than TDC?
4. I?ve read that 60s ?70s, 35 hp ?55 Chrysler?s tune-up specs are basically the same, is that true? And Force??

Old Post:
What year model is your engine? What is the point gap spec for your engine? My 1968-70 35HP Chrysler is set at .020 point gap. I assume this is at TDC or I know it from specs. It runs good at the setting. If needed, I'll check to see if my points are set at TDC and possibly what yours should be set at. I'm almost sure my point's widest gap is at TDC. I'm almost sure setting the proper point gap is setting your timing properly. Is that correct?

Good Luck,
JOW

Re: i need help how to set points on force 50

I have a Clymer Outboard Service Handbook on Chryslers from the Public library that covers engines 25 hp ?135, 1966 ?1977. My personal interest is my 35 hp and up to 55 hp. The breaker point gap is .020 on the 35 hp and most 45 hp ? 55 hp (except some series at .015). It shows 35 hp ? 75 hp timing at 32 degrees BTDC. I see why a manual is recommended due to the Specs ?not to mention the procedures? of setting breaker points and timing.

My tuning/timing on Tecumseh Lawn Mowers and VW?s static timing had ?me? in tune in 1985 vs now. My 1970 Chrysler 35 hp engines has been very nice since 1985 when I purchased the 15? Raycraft & 35hp Chrysler. I have not had a points, timing or impeller issue. I possibly changed the points and plugs once but not the impeller. I?ll change the impeller by next season but I doubt it will be as good as the one I checked in 1985 and the past summer. I would like to see if a new Sierra impeller will change my aerated looking cooling water (even though the engine has never run hot). The fatigued/shape of the impeller is what I feel is a problem.

Good Luck!

Frank & Chrysler Techs, Please help ID the mark in Chrysler 1970 35 HP magneto system

Frank & Chrysler Techs, Please help ID the mark in Chrysler 1970 35 HP magneto system

Frank & Chrysler Techs, Please help ID the mark in Chrysler 1970 35 HP magneto system as a ref mark or not.

I would hate to break my engine down to see if the mark has ref to TDC, widest point gap or timing. I thought it would have been ?shown and addressed? in Clymer?s Chrysler outboard Service Handbook 25 to 135 hp ? 1966 ?1977. If it was I missed it. Or! Does the mark on the cam (? I think?) represent the highest point of point gap opening? Or! The 10 degrees past the highest point mentioned in Clymer?s service handbook on ?alternator models?? Or! Is the ref mark for setting the other set of points mentioned in the handbook? If so, why is that step necessary if you are going to set the second set of points as the first set (identifying the same location?)?

If you have an attachment showing the mark, please share it. I feel it should be showing on some of my Pics. The reduced quality is not allowing it and that was not my focus at the time of the Pics.

Thanks In Advance!

Re: i need help how to set points on force 50

Frank's reply below in another thread to the above post might help you as it will help me. Bottom Line! Some skills and time will be needed to get basic fixes and the best performance. Good Luck! JOW

First, before we get into marks, it is necessary to understand that setting point gaps must be done ACCURATELY on each set, as small--extremely small differences between them cause bigger differences in timing between the two cylinders and loss of performance. So: Some Chrysler engines had two marks on the flywheel 180 degrees apart for TDC of each cylinder. That way you could test the timing on each cylinder to be certain they were both the same.

Some cams have a mark on them, some don't. Some have an arrow indicating direction and when installing the cam, the arrow must be up. The mark makes it easy to be certain both point sets are set at the same height on the cam-- If you only had one set of points, you would not need a reference line.

I never read the 10 degrees past in Clymers and I always set my points to .020 at the high spot on the cam or the mark if it has one. Most of these cams I have seen have a long dwell time so the high spot is a segment, not a point, and easy to find. Quite Frankly--no pun intended-- I don't set them much any more and this is the kind of thing I analyse when I get the flywheel off, then decide where to set the points. If I get it wrong, no biggie: I just pull the flywheel and do it again like I say below.

BTW: I have spoken to some old time Chrysler mechanics who insist the two cylinder engines run better with the points at .016 but I have never tried it. I can tell you that my alternator 50 started and ran with less than a .005 gap. Started and ran way better when I re-set them to .020

At any rate, you are not going to ruin the engine if the points are a little off and if you don't hit it the first time simply pull the flywheel and try again.

thanks for the info on my points i set them at the high point on the cam i have not had time to run the motor yet but when i do i will keep you posted thanks again

Re: i need help how to set points on force 50

Sounds Good! Have you used muffs or a barrel to start it before driving too far? Over the years, I have learned to start my motor vs running my motor for seconds before driving excessive (75-120) miles to fish. I have to admit it has not always been with muffs or in my barrel except the initial start of the season. Then, I would let it idle or run just above until the cooling water starts flowing and medium instant powering 2-3 times. Plus, I learned light power in the barrel is no sub for full power in the lake (even if I stay on the trailer for the full power test) WOT!

Good Luck!

i finally run the motor the other night seems to run fine but i have it in the garage with a barrel of water dont want to pop it in to gear though for it will shoot water all over my garage i do have a pair of muffs now so when i get the rest of the boat done i will pull it out of the garage and rev it up in gear thanks i will keep you posted
