CARBS THE PROBLEM?

[critter34]

I talked to a few marinas and they said the carbs are clogged up thats why my boat wont plain off but when its not in gear it sounds like its running great until i put it in gear and all the way foward thats when it sounds weak could dirty carbs do that?

Yep! and a few other things as well.

You need to do a spark test,compression test and take a fuel sample.

Little sense in rebuilding carbs on an engine missing spark on a cylinder or two.

Less sense doing it on an engine with compresion problems

No sense rebuilding carbs and putting bad gas back into them.

What DHP said.

You will get a lot better answers if you tell us what make and model engine you have, critter.

Seems I have seen this question from you before. Is that just my imagination?

Re: CARBS THE PROBLEM?

An engine running on half its cylinders will rev to the moon with no load. That proves nothing. Do the basics. the engine needs spark, fuel, air, compression, and it all needs to happen at the proper time. Missing any one of these and you have a poor or no-run engine.

Next time you're out, have someone pump the primer bulb when it boggs down and see if she goes. Also try hitting the choke(Primer) and see if it picks up...

i have tried that she drowns ,i think its in the prop anyone know what i should be runningfor size and pitch ?its a 1972 starcraft 17ft aluminum the prop was off a 17ft fiberglass tri haul

Re: CARBS THE PROBLEM?

the prop is not the problem, the fiberglass was heavier, so it should pop right up. do the things DHP suggested. this will tell us the condition of the engine, you have to trouble shoot in a logical order, not just throw $ and parts at it. get the answers we ask for, to get the best advice. save time and $

Re: CARBS THE PROBLEM?

ok use one post or the other, you post compression on the other post and not here. were gettin 1/2 info on each post. you posted the compression is 140 on each cyl. what about the spark, how old is the fuel. when you took the carb apart did you soak it , blow it out with compressed air and reassemble with a rebuild kit? if you didn't you wasted your time. if you think i am chastizing you, i am. it wastes our time to get half the info. go to the engine faq section read the post on carb adjustments. as is said before there is a reason we do things in a certain order.

Your absolutly right it wasnt prop,i was used to hearing a two cyl.and thats about all that was running ,one carb had a plugged jet that air would not blow out everything was new in carb previous owner put them in but could not remove bottom jets floor rotted in tri haul and the guy gave me everything i tried to pay him for the boat motor and trailer but he said mount him a deer head and so now i have a sweet running 70hp johnson thanks to everyones help oh the spark plugs had a gap of about .100

i have basstracker,1992 40hp johnson, i've had 2 marinia's work on it neither fixed problem, motor idles fine, but when you give it gas to go fast it boggs down, but if i push in the key for the choke and hold it in boat will run fine,marnia rebuilt carbs, new prop,by passed oil separater. gas tank bad so now use portable, putting in new spark plugs tomorrow,plugs were very weak and had oil on plugs, not sure what oil mix should be. any help would be app.

Did they check your fuel pump?
