I am pleased to report that I have successfully re-directed the excess gas from my exhaust into a container. I have also changed over to a full-synthetic oil. I can’t BELIEVE the difference this makes! I should have taken pictures of the water in the trash can after idling this motor for a while before switching to synthetic and modifying where the unburned gas goes. GROSS!! Now it looks like you could drink it. Ha ha.
So this is what I did. I bought part 302033 on eBay for just under $8. That way, I could always go back to stock if I screwed something up, or if I want to sell the motor stock.
It had some ridges on it where I wanted to put my nipple, so I filed them off. I drilled and tapped the hole to match the 10-32 threads on the nipple. The resulting piece looks like this:
I bought a Beswick Engineering nipple elbow on eBay for about $7 that was kind of like a miniature banjo fitting. It is a 90 degree fitting with an o-ring up against the mating surfaces. It also allows you to adjust the elbow to any direction that you want when you tighten it down. Very convenient for this application. I wanted to use 1/8 fuel hose from O’reilly Auto Parts to match the 1/8″ holes in the engine block, and this fitting was perfect.
I used some epoxy to fill the drain hole to the exhaust.
It all seemed to fit together nicely. I painted the cover plate, and put the gas line on the elbow. It fit incredibly tight and I could hardly get it off again. I screwed the elbow onto the cover plate and installed it on the motor.
I zip-tied the new 1/8″ line to the nearby quick-connector so it wouldn’t get yanked out.
Initial tests are fantastic!! I have attached a video of my motor idling and the amount of gas coming out of the hose.
Now I just need to get a more appropriate container and go try this out on the water. Thanks again for everyone’s help!
