Oh dear count to ten

Nope impulse from the crankshaft caseing. I'm sure it has one.

On the understanding that the saw was OK prior to the oil misshap, then the problem is almst certain to lie with the disturbance of the carb for cleaning.

 

The fuel pickup hose may have fractured when disturbed, so the fuel pump is not able to lift fuel, drawing air instead.

 

Or, the carb has not been reassembled properly,

 

Or, it could be that the impulse line has been disturbed or broken, but my money is on one of the other two options.

Sorry - 010................ I am pretty sure this saw has an impulse pickup that goes through the carb manifold and it is important that the gasket lines up with the hole in the manifold, I reused the old one and made sure it lined up on the rebuild.

 

I reckon the oil has been pulled through the carb and may have blocked the jets or H&L metering part of the carb. It may need a complete strip down and a good blast out with carb cleaner or an overnight soak in white spirit to clear it out - the filter may also have been impregnated with the oil.

 

If you have been trying to start it on full choke, the saw may be flooded so it is worth pulling the plug out, pointing the saw vertically and pulling it over to clear any puddled fuel - the plug is worth heating with a plumbers propane torch or gas cooker hob to get rid of residue fuel/oil.

 

If you have a can of carb cleaner, take a note of how many turns the H & L screws are to reach their stop and then remove and blast carb cleaner through the jets and replace - I reckon if this is done and the impulse holes line up, the saw should start.

 

You may get through it by just getting the saw going by pouring a little fuel down the plug hole and eventually it will pull the thick oil fuel mush up through the jets but it may take a while:thumbdown:

You guys are a great resource for numpty's like me. I have to admit with a little egg on my face that Gardenkit was on the money with a carb reassembly issue.

I only went and put the metering valve back upside down:blushing:

Flipped it the right way round and she's ticking over again, all be it a bit smokey:001_rolleyes:

Thanks everyone for taking the time and not taking the P

Cheers,

Si

I was just about to suggest you check this, but reading down you're already there!.

I was going to suggest this because I made exactly the same cock up the other day.... The metering diaphragm orientation is counter-intuitive to me....
