Slow Start

[dave lowry]

Our 455 seems to be taking longer and longer to fire up after having sat
for anything more than over night. I suspect we can fix it by having an
auxiliary fuel pump put in, but could we also fix it by having the Q-jet
overhauled?

Dave,

Just a guess, but one possible cause could be fuel "draining" from the carb
float bowl ( this doesn't have to show up as an external leak ).
I would have it checked out before they install the electric pump and maybe
"cover up" the original problem.

Did you get your Onan fixed?

Maybe I could get that fixed without a full overhaul.

Onan being worked on as I write.

Thanks Tom. I'll have the mechanic check it out.

Dave I have never seen a check in Qjets but someone said the fuel pump has
one to stop bleeding back to tank i use my carb filter and u get 12000 miles
on filter and i could set my watch on this

 

[dave lowry]

Thanks for the suggestion. I'll pass it on to my mechanic. I'm pretty sure
he'll be pulling the carb to seal the holes in the float chamber.
