adw is on the money! Diolch yn fawr

Cheers adw, I'll dive out to the barn and take a look now. Just found the manual to and the 350 is a bit of an anomaly in the range?

Cheers Spud, The problem is I cannot find a pickup pipe in the oil chamber? On my 044 there is the rubber tube and strainer. On here - nothing. I will see if I can a schematic to give me a clue?

I stripped down the bar oil pump assembly down on my old 350 for the first time today and noticed that unlike my other saws this one does not appear to have a bar oil filter? From what I can see there is a port through the pump body going to the bottom of the oil chamber from the pump head and that is it. Am I right?

Well it is now running. Reliably. Maybe. The spare saw green flex impulse hose also didn't look good (cheers Spud) so I found some silicone hose around the same size and fitted that. Also installed the carb from the parts saw. The settings on the old carb were L-3 turns out/H - 1 turn out. Started and ran. Settings now L-2.5 H-1. Fingers crossed?

Saw re-assembled and run up last night - also checked and cleaned the oil pump. Was pretty bunged which is probably why it appeared to be 'over oiling'. Oil way was bunged so the lube was finding an easier and alternative route. Set the carb to 1 turn out on the LH. Fires on first kick with choke applied then knock the choke in for fast idle and it will fire easily but immediately red lines. Blip the throttle and of course the idle backs off and after some fine fettling of the carb it was idling nicely. After 20 mins of idling/blip the throttle etc I decided to refill the bar lube and fit the bar. Now it won't idle. I will get back to it tonight as I ran out of time and patience ?

Link?

I used the same size but salvaged from the low hours (but fkd) parts saw. Hose would not fit down the hole so I opened it up ~0.5mm. Fitted snug then.

Cheers Spud. Good to know I might be on the right lines? Drilled out the fuel line port in the top of the tank so the 'parts saw' fuel line which was good would fit through tight. Applied a coating of fibreglass gel as it went through and a bit on the outside. Hopefully that will work?

Cheers for the suggestion Stubby.

Well saw is now stripped. Delayed due to beer and BBQ. Two problems found. 1. Small what looks like silicone ~8mm dia. connection to lower crankcase from carb back plate was split. Swapped with a good one from the parts saw. 2. Fuel hose split at the filter. May have happened as I was removing it for checking but if it did it was brittle anyway. How to change it though as the tank/handle assy looks to be welded together after the hose is fitted through via the hole by the vent filter? Open up the hole a bit to suit a new hose then seal?

Cheers adw, Thanks for the suggestions. Next job carb off (easy) and tank out then (sus it as I go) Apparently he bought it 18-20 years ago for general firewood work. But yes a cheaper end of the range saw but worth a go as it was FOC?

Idle for 5 mins the use for 25'ish.

It's on my 'todo' list
