Been working on a 12Q and wanted to replace the gasket between the air cleaner body and the carb. The IPL gives the same part number for both primer and choke carbs - 692667. Problem is that it's not the right shape, the hole for the air to pass from the primer valve to the carb doesn't line up. I have a similar gasket 795629 in stock but it's not that one either. Any suggestions.
On a different tack, looking at the manual I see that the recommended plug gap is 30thou for horizontal crank engines and 20thou for verticals, no mention of model numbers, just horizontal and vertical - why?
