I wonder if one could buy the shroud and air box, (All the plastic) off the new design briggs and put it on this engine ? Seems that would be the best fix ?
Speaking of that..... I had the very same thought.... I think there is a high probability that it would work.... (B&S will NOT confirm this)
My model is: 446777-0244E1
The revised model with the cartridge filter: 44P777-xxxx
I compared my parts list (446700 with type 0025-0365 : MS5195.pdf) vs revised engine parts list (44P700 with type 0016-0884 : MS3581.pdf)
part# 792301 - Blower Housing (ref# 304) $40.60
part# 795120 - Air Cleaner Cover (ref# 968) $14.50
part# 790697 - Air Cleaner Knob (ref# 467A) $2.30
part# 791237 - Trim Plate (ref# 1040) $11.20
part# 792297 - Intake Elbow (ref# 431) $13.15
part# 790690 - Housing to Elbow screw (ref# 305B) $1.40
part# 792105 - Air Cleaner Cartridge (ref# 445) $17.95
part# 792303 - Pre Cleaner Filter (ref# 967) $5.95
Parts that are identical between the two engines (identical part#)
Flywheel (ref# 23)
Blower screen (ref# 73)
Control bracket (ref# 222)
Intake manifold (ref# 50)
The only part that is questionable (?????)
Blower (ref# 1005) my engine requires #698760 --- new engine requires # 791236
**** not sure what would be the difference between the two blowers.
The total cost in parts would be $110.75
(according to B&S website pricing) ... less/sans any taxes and shipping costs.
Since B&S will NOT verify if this would work...... not knowing the difference between the two blowers would put some questions into the retro fit project.
I'm gonna check my local area if there are any "salvage yards" for lawn tractors..
who knows.... maybe i'll be lucky to find all the parts needed for the retro fit at a lower cost...
