Steam and a hickup

[mikes 86]

I have 86-125/4cyl every time i start the motor i get like a small hickup or back fire through exhaust and on the next turn of the key it fires right up and runs great, not that big of a dill but it is bugging me and i know that it is not right, 2nd problem it seems that i am gitting steam out of exhaust at idle in gear, is this normal or do i have a problem i need to address!!!!!! Thanks for any help

Re: Steam and a hickup

It's very common for the Force motor to "hickup" when starting. As long as it's not a loud bang, not sure I would worry too much.

Steam out of the exhaust is normal. More noticeable when the air temperature is cold. Hot summer day in the 90's, you still may see some steam but not much. You may want to verify that your overheat alarm (buzzer) is working.

Re: Steam and a hickup

If you're only seeing steam and no water then you may have a water pump problem. Steam AND water is good on cold days. Here is a video of mine in the summer on muffs. It pumps water within 4-5 seconds..note this is a cold start. Make sure you're pumping good water. EDIT...When I turned my idle mixture screws to 1 turn out I noticed it was much harder to start annd was backfiring or igniting out of the exhaust...one explosion was so big it shot water everywhere when it had it in a tote of water. I turned mixture screws to 1.5 turns (just for land running and it fires up good with no backfiring. Also are you using fast idle to start? Might check out your idle mixture or clean carbs. http://youtu.be/qAD6MAru5hA

Re: Steam and a hickup

The steam is normal.The pressure relief system if working,will shunt water to the exhaust snout.
Once you speed up the motor it will open and should come out the 2 holes in the back of the mid section.
Like pnwboat says check the buzzer and do a compression test.
Set the air screws between 1 and 1/16 and 1 and 1/8th out for initial settings.
