I agree about HF at $235. I would not put that amount into a HF China Covid 19 engine. Although I've heard good service from the 5 hp HF predators at $100 with a coupon. You can usually find coupons on-line.
The Honda engine will only use as much power as it needs, so yes, most likely a fit, but might be little more gas consumption. You can cut down on gas consumption by installing a auto idle when the splitter wedge is at rest.
Them old old model 7 and 8 hp manual or electric start briggs are not worth the effort to do major repairs. I have a old model 8 hp electric start Briggs that I nurse along is how I know such.
Your Model number info is usually stamped into the air cowling on the edge by the carb side on the old ones and sometimes you have to remove the cowling and carefully inspect with a magnafying glass to find such and even harder to see if someone has painted over it. If it's severly rusted you can sometimes take a damp cloth and gently wipe over the rust and you will start seeing the stamped info on the air cowling. Save your old engine if it's electric start, the same parts, starter, flywheel, stator and even the carb will fit the older Horiz shaft Briggs from about 7 hp to around 11 hp, I think.
Them guys at the link I provided are small engine pro's but they have to have original Model info to give a logical answer.
