520H Intake manifold question

[SadieCoonhound 8]

I need to remove the intake manifold to clean the carb. Will I have to remove the muffler?

I'd like to order all the gaskets before I start this.

its an Onan P220. Would appreciate a source on where to order parts from. 

Thanks.

Ive taken my carb off with out removing the intake manifold. Its tight but it can be done.

[SadieCoonhound 8]

The bolts are on the bottom of the carb. What are you suggesting?

[woodchuckfarmer 333]

Ive got a wrench bent up at an angle to slide under the carb and turn the nuts

.

I'm assuming a long l-shaped box end. Going to give it a try. I thought the bolts would be to long to come out from the bottom. 

Thanks

I think there about 1 inch long.

[SadieCoonhound 8]

Thanks. Worth a try.

the length of the carb to manifold bolt will depend on the spec letter of the engine.

spec A-B  1" to 1 3/8 " X 5/16

spec C and beyond 1 3/4" to 1 7/8" X 5/16

 

thank you. boomer ( the used onan engine parts guy, also NOS and new )

Funny. I spoke with him and am ordering parts. 

Thanks.

The onan service manual says the card can be removed with a crows foot wrench. 

Or a short 1/2 inch open end. 

I did it the long way. Removed the muffler, heat shields, etc. 

Read the manual too late.
