Checked the head gasket and the crankcase O ring are both in good condition. The bore from what I can see through the exhaust shows no signs of scoring. Tested the decompressor and it is working as it should.

Replaced the both the air filter and carby diaphragm with brand new ones to see if they were the cause but it has made no difference. There are no fuel line or other blockages. It happens even with a full tank of fuel and with the grasscatcher empty.

Any ideas of what the issue may be as I am currently at a loss.

Thank you.

Hi Cheese,

Could be a fuel thing causing the problem but if you just check these first.

1. Check fuel cap to make sure that the pin hole in it is not blocked.

2. Check fuel flow when the fuel tap is turned on.

3. I am assuming this has a plastic carby on it and if so check that the screw jet is not blocked.

4. Check mounting block is not loose.

5. If loose check the 'O' ring behind the carby mounting block is not damaged.

6. Also check the 'O' ring on the mountint block has no damage.


Try these few things and let us know what you have found also pictures of the machine and also the carby area would help as well.
