I found the same thing, occasionally- I would cut the clear plastic around the inner and outer edges, then carefully peel the plastic off of the gasket. If it tore, I had extras, but it still wasted...

If one riser was warmer, it's fairly normal at idle, but at higher RPM, it indicates a problem. If it was on the trailer, don't run it at high RPM- the water supply usually can't keep up with the raw...

I never needed to remove the cover, so, no.

.7VDC-4.2VDC is fine but the code still bothers me. Disconnect the battery for a half hour, reconnect and check for codes again. If you see none, start...

21 is TPS High, 33 and 34 are MAP sensor and 14 is ECT High Temperature.

The MAP sensor attaches direct on the intake- look at this link for a rectangle on top with two screws, along the far edge...

I don't remember the default for defective MAP, but the TPS defaults to 12. Make sure that's operating correctly, too. I don't know if they would run it this rich if the MAP were to fail, though....

That's for 55 gallons and it's rated to -55 degrees F. Far better than the pink stuff and the engine only runs with that, not water- lubes the impellers and displaces ALL of the water. Also, if each...

You have a carb- you can spray fogging oil in until the engine smokes like someone playing the slots at a casino, but ask if the oil will actually smoke- some don't and one has a blue/white label...

Shift linkage- if you can get it to crank after jiggling the throttle when it's able to shift means the cable probably needs adjusting.

It has TBI, remove the flame arrester and watch the fuel as it sprays in- if it looks like the 'cone' has gaps, it could be low fuel pressure or dirty injectors. If you have a fuel pressure gauge,...
