Re: invader problem

O.K. your saying your 20* just to start,, way to much, get no1 back up to tdc on compression, pull distributer and reinstall sounds like you may be off still in that department, re-time with timing light, you'll get there yet you've already come a long way since Saturday, hopefully all is good, I'm going to be leaving town until Monday later today, going to get my boat out of storage and install new intake and carb, as well as new trim tabs. I'll check with you on Monday. Hopefully someone else will be able to help you out lots of good people on this board.

Re: invader problem

I have discovered my no1 cylinder stays dry while the other 3 are wet. I have done a compression test, all 4 are around 120 psi, I wasnt able to tell if it holds pressure. Am I looking at the top end or the bottom end?

Re: invader problem

Wildcat I'm back how did you make out?

Re: invader problem

Hey northern, good to see you back. I wound up pulling the head due to the no1 cylinder staying dry...wasnt sure what else to do. I dont know how any of the valves were seating, lots of carbon and pitted seats. Many hours later with a hand lapper, I think were going to be ok. I'm now waiting on gaskets, they should be in some time this week, with any luck this will solve the problem. I will keep you informed. Thanks Northern

Re: invader problem

Hi Guys!<br /> Hope you don't mind me hoping in but I've got pretty much the same problem. Timing belt seemed to have jumped when the water pump seized because the points were between two lobes on the distributor cam when I had tdc on compression stroke. Am I right in thinking that it should be 0* on crank, the hole in the cam pully in line with the mark on the rockercover (valve cover) and the mark in line on the pulley for the distributor axel. At this time shouldn't the points be on or just before a lobe?<br />Clive.

Sorry forgot to say it's a aq151 from late 80's

Re: invader problem

When you have your cam,crank and accessorie gears lined up with their individual markes, your rotor should be pointing at your no1 spark plug wire. Your points should be open at tdc on the compression stroke. Hope this helps...good luck

Re: invader problem

Wildcat are you getting the head reworked at a machine shop? nows a good time to make sure valves are strait, Clive wildcat is correct. good luck guys, hope you get to water soon, I'm just about to start tearing into my boat as soon has we get some weather of it not raining or freezing, Wildcat are you sure if all cyclinders were getting spark.

Re: invader problem

Hey Northern, good luck on your boat. All four cylinders have good spark. I redone the head myself. The valves look good. The head was extremely dirty...dont know how the valves could actually seat. I gave her a good lapping, should be ok now. Just finished installing everything back together. We will see what happens tommorow.

Re: invader problem

Good stuff Wildcat...I'll watch for the outcome, this post is like watching a good mini-series.

Re: invader problem

I have come to the conclusion that my no1 cyl is still dry. Pressure test I guess. Solving this problem shouldnt be rocket science, but it sure feels like it. Almost ready to take it to a professional.

Re: invader problem

I fired my 350 up yesterday this is what I got, hard to start at first, pulled a plug from each side, wet with fuel,once started and burned fogging off, warmed her up, shut down pulled same two plugs and they were dry and hot, so are you getting a dry plug after running or when attempting to start,therfore I would assume dry plug tells me cylinder is firing correctly, wet plug would be flooding or not firing at the correct time or not at all...I wish I could see what you got. The only thought that I have is your cam timing is still out, you have a bent or stuck valve on No1, or a badly worn distribtor shaft ( I had this on a merc 3.0 caused all sorts of timing and running issues) If all the above is fine then maybe its time to Throw in the towel and see the pros and carry a fat wallet...Keep me posted Wildcat I'm starting to treat this like it was my boat.
