Icing

(1/2) > >>

Thomas:
Had this happen twice now. After driving the 36hp for about 15-20 minutes the car starts to run crappy and dies. If you try to start it's like the carb is flooded. If you let it sit for 15-20 minutes it starts backup. The intake manifold below the carb is ice cold and I have seen sweating in that area. I'm sure it is an icing problem and after looking on the internet it would seem that the heat riser tube is plugged so I removed the intake manifold. It was all clear so that is not the problem. The motor is bone stock except for being updated to 12 volt. Does anyone have any ideas that what could also cause this icing problem. Thanks Tom

you should ask zundfolge haha pm sent  :)

Thomas:
Woops sorry I thought it went into general forum. After taking off the intake and finding out it is clean I started to do look for ideas on the internet (was up way too late last night). On Samba they talked about the distance that the peashooters should go into the muffler as being critical for how the vacuum effect works on the preheater tube. After looking at mine I was about an inch and a quarter to short on that distance. I'm hoping after reinstall the manifold and adjusting the peashooters this will solve the problem. Has anyone else ran into the peashooter distance problem before?

Thomas:
After putting it back together I adjusted the pea shooter in until I got the right flow (helps if you have a FLIR Camera you can use). Below are some thermo shot before and after.

The position of the pea shooter in the muffler makes a big differance.
