I have the 25 hp Subaru in my 2425 and i put a hotter plug in mine also opened the gap in the psark plug up about 3 thousands more than it called for and it helped alot on my cold start issue. Will go back to cooler plug in the summer months.

Just pulled out the plug and went to local parts place asked for a hotter plug. The spark plug has a number on the side of it, then gap it 3 thousandths more open than what the manual calls for. You can google the specs for your engine and what factory reccomends

Let me know if it helps, it did for me

I didn’t know what model of engine you have, they have several and as many spark plugs to go with them as well
