OX66 gremlin

[DLAB]

I made a post last week about the LP Pumps, changed them, still had a problem. Got mad, came home cleaned VST, checked o2 sensor and sure enough the barbel was clogged solid with carbon. Cleaned all that, replaced the 02 sensor with another one I had already cleaned. Went down the road to the river, ran better but still a little rpm drop off. Came home read every ox66 gremlin thread on the internet and one of them paid off! Turn your attention to #15, that little screen had a solid gel like coating on it! Cleaned it, ran the boat, everything runs like it should!!

Just thought I'd pass this info on in case anyone else is chasing a gremlin!

Did you have a problem at Idle also ?

Now that you mention it, I did have a lean sneeze at idle before and didn't notice it Saturday after getting everything clean. Of course I would contribute the lean sneeze to the o2 barbell being completely clogged with carbon. I had to use a drill bit to clean it out

I did kind of rig it though The local boat shop didn't have a vst tank seal, so I snipped about a 1/4" in the loop of the used one, superglued it together, then put a dab of gasket maker on the seal! Hey it worked! I also put a small dabs of the gasket maker on other parts of the seal to hold it on, last time I pulled the VST I had hell getting it back on even with a new seal, it pops out and gets aggravating! I will do this every time now! Made it very easy to reassemble

Good for you, now run sea foam more regular and amsoil and you'll never have to do it again!!!!

[eldridgegolf]

what does the amsoil do for your motor

I ran it with sea foam and after 6 years and about 900 hrs it blew because of ethanol, but the engine was spotless inside absolutely zero carbon.
